- - - - ALGINATE HYDROCOLLOIDS
        
        THEIR NAME DERIVES FROM "ALGAE" (THEY CONTAIN SEAWEED)
        
        LESS PRECISE THAN REVERSIBLE HYDROCOLLOIDS, BUT CHEAPER AND EASIER TO USE
        
        THEY CAN CHANGE COLOUR WHEN THEY HARDEN
      - REVERSIBLE HYDROCOLLOIDS (AGAR-AGAR)
        
        THEY NEED TO BE HEATED AND REQUIRE TRAYS THAT ARE COOLED IN WATER
        
        THEY ARE MORE COMMON IN THE LAB (FOR DUPLICATING MATERIALS)
    - - POLYSULFIDES
        
        LESS USED, SUITABLE FOR DENTURE IMPRESSIONS
      - CONDENSATION SILICONES
        
        THEY CONTRACT MORE AFTER HARDENING
        
        MORE COMMON IN THE LAB FOR MATRIXES
      - ADDITION SILICONES (VPS)
        
        MORE PRECISE AND COMMON
        
        LESS HYDROPHILIC
      - POLYETHERS
        
        MORE HYDROPHILIC
        
        LESS COMPATIBLE WITH OTHER CASTING MATERIALS
      - DIFFERENT VISCOSITY
        
        PUTTY
        
        MORE RIGID
        
        USED AS A SUPPORT FOR MORE FLUID ELASTOMERS (LIGHT BODY AND WASH)
        
        HEAVY BODY
        
        USUALLY COMBINES WITH LIGHT BODY ELASTOMERS AS A SUPPORT
        
        LIGHT BODY
        
        USUALLY COMBINED WITH HEAVY BODY ELASTOMERS FOR DETAILS
        
        EXTRA LIGHT (WASH)
        
        MORE FLUID
